Primary Ovarian Insufficiency

Brief summary

The goal of this study is to assess the effects of higher doses versus standard hormone therapy on quality of life (QoL), symptoms due to estrogen deficiency, and bone health in women with premature ovarian insufficiency (POI). The efficacy of the hormonal treatment will be assessed clinically and also by measuring serum concentrations of Estradiol (E2), Follicle-Stimulating Hormone (FSH), Luteinizing hormone (LH), total Testosterone (T), Estrone (E1), E1 sulfate (E1S), and Sex Hormone Binding Globulin (SHBG). Bone mineral density (BMD) will be measured using dual-energy X-ray absorptiometry. Safety will be assessed by measuring endometrial thickness with Gynecological transvaginal ultrasound (TVS), treatment-related adverse events (AEs) and treatment-emergent AEs monitoring.

Intervention model description

Women with POI taking standard-dose estradiol hormone replacement therapy (E2/dydrogesterone (oral) (2.0/10 mg)) were invited to the study. We conducted a pilot study designed to compare the effectiveness of oral estradiol (2mg/ day) and Transdermal estradiol gel 0.1% (Gel sachet 1.0mg/ day) as standard-dose estradiol hormone replacement therapy. The obtained results on the absence of a significant difference in the effect of the above therapy made it possible to justify the prescription of higher doses of estrogens without prior switching from oral to transdermal therapy in equivalent doses in all study participants. Study participants will consistently receive Transdermal estradiol gel 0.1% (Gel sachet 1.5mg/ day) and Transdermal estradiol gel 0.1% (Gel sachet 2.0mg/ day) (both with 200mg micronized progesterone administered vaginally for 14days per cycle) with an outcome assessment at each stage of the study.

Inclusion criteria

* Patients with karyotypically normal spontaneous POI diagnosed before the age of 40. POI as defined by: change in menstrual function (oligomenorrhea and/or amenorrhea for at least 4 months), elevated serum follicle stimulating hormone (FSH ≥ 25 IU/L with 4 to 6 weeks interval) * Between 18-45 years of age * Use of standard-dose estradiol HRT (Estradiol 2 mg+ Dydrogesterone10 mg) for at least the last 12 months * Signed informed consent before inclusion in the study

Exclusion criteria

* Any contraindication to HRT per the current drug labels. These could include, but are not limited to: history of venous thromboembolism, estrogen-sensitive cancer history, regular cigarette smoking and history of or active liver disease, bleeding from the genital tract of unknown origin, etc. * POI due to cytotoxic chemotherapy or radiation therapy, surgery * Diseases that may be associated with hot flashes (such as pheochromocytoma, hyperthyroidism, medullary carcinoma of the thyroid, acromegaly, pancreatic islet-cell tumors, renal cell carcinoma, carcinoid syndrome, systemic mast cell disease, neurological flushing, emotional flushing, spinal cord injury) * Taking medications that can also cause hot flashes (such as Tamoxifen, Raloxifene, Tricyclic antidepressants, Monoamine oxidase inhibitors, Calcium channel blockers, Depo leuprolide, Clomiphene, Serotonin uptake inhibitors) * Severe somatic conditions (uncontrolled hypertension, kidney disease, liver disease, etc.) * Diseases with impaired thyroid and adrenal gland function * Refusal to participate

Design outcomes

Primary

MeasureTime frameDescription
Evaluation of the severity of estrogen deficiency symptoms3 monthsThe Green scale questionnaire was used initially and after 3 months against the background of HRT. The questionnaire includes 21 questions from 0 to 3 points, where a lower score means a better result.
Changing the assessment of quality of life using the Short Form Health Survey-36 (SF-36)3 monthsThe SF-36 is a generic QoL instrument. It consists of 36 items organized into eight domains: Physical Function (AF), Physical Role Function (RF), Bodily Pain (BP), General Health (GH), Vitality (VT), Social Function (SF), Emotional Role Function (RE), and Mental Health (SM) as well as an item on the change of General Health. The scores of each domain have been converted into a scale from 0 to 100. Lower scores are indicative of worse conditions.
Changing the assessment of menopause-related quality of life measured using the Menopause-Specific Quality of Life (MENQOL) questionnaire.3 monthsThe MENQOL questionnaire is a self-administered instrument. This validated questionnaire (range 1-8) assesses four quality of life domains; physical (16 items), vasomotor (3 items), psychosocial (7 items) and sexual (3 items). Scoring generates 4 domain scores and a total score, the mean of the 4 domain scores. Identical scoring for each of the four MENQOL domains is used. A 0 is identical that the woman has not experienced this specific symptom in the previous month; Score 1 demonstrates that the woman experienced the symptom, but it did not bother her; Scores 2 through 7 demonstrate an increasing level of the bothering symptom, so that these scores indicate increasing levels of bother experienced from the symptom and correspond to the ''1'' through ''6'' checkboxes on the MENQOL. With increasing MENQOL scores, levels of bother experienced from the symptom are increased as well.
